Control Method of Active Control Engine Mount (ACM) to Decrease Engine Vibration from ACM and Front Driveshaft

Abstract

ACM reduces body vibration to decrease vibration of under point in engine mount. Recently, gear of transmission needs higher connection to increase more powertrain efficiency. But engine vibration transfers more to body from front wheel driveshaft. We construct new ACM control for reducing the engine vibration transmission to the driveshaft without new parts adding. The new ACM control decreases body vibration to control vibration from engine mount and driveshaft at 2 control point away from 2 engine mount.
